Artificial photosynthesis bringing new vigor into plastic wastes
AI summary Read the abstract
This review explores how artificial photosynthesis, which uses sunlight to drive chemical reactions, can convert plastic waste into valuable chemicals and fuels. The approach works under mild conditions and offers an energy-saving alternative to traditional plastic disposal methods like landfilling or incineration. While still in early stages, this technology could help address both plastic pollution and the need for sustainable carbon resources.
Abstract The accumulation of plastic wastes in landfills and the environment threatens our environment and public health, while leading to the loss of potential carbon resources. The urgent necessary lies in developing an energy‐saving and environmentally benign approach to upgrade plastic into value‐added chemicals. Artificial photosynthesis holds the ability to realize plastic upcycling by using endless solar energy under mild conditions, but remains in the initial stage for plastic upgrading. In this review, we aim to look critically at the photocatalytic conversion of plastic wastes from the perspective of resource reutilization. To begin with, we present the emerging conversion routes for plastic wastes and highlight the advantages of artificial photosynthesis for processing plastic wastes. By parsing photocatalytic plastic conversion process, we demonstrate the currently available routes for processing plastic, including plastic photodegradation, tandem decomposition of plastic and CO 2 reduction, selective plastic oxidation, as well as photoreforming of plastic. This review concludes with a personal perspective for potential advances and emerging challenges in photocatalytic plastic conversion.
